Description
Product Description
The IC694ALG233 by GE (Emerson Automation) is a 16-channel high-density analog current input module for the PACSystems RX3i platform. It is engineered for precision measurement in demanding industrial applications, supporting sensors that monitor flow, pressure, temperature, and other process variables. Each channel can be configured for 0–20 mA, 4–20 mA, or 4–20 mA Enhanced mode for superior flexibility and accuracy.
The module offers 16-bit resolution, advanced diagnostics, open-wire detection in Enhanced mode, and full software configurability without jumpers. It supports hot-swap for minimal downtime and provides detailed status reporting to the CPU, including module and power-supply health.
